And you don't mention any HIV concern.
Leave.
You said you had protected sex, so your symptoms are unrelated to ARS and you have no reason to test. See your doctor if you itch doesn't clear up.
I hate window periods, might I add. It's just baloney that changes depending on who you ask. TripleH says 6-8 weeks, Dr. Bob says 3 months, Teak says 12/13 weeks, Mass (the state I'm from but don't currently reside in) says 6 weeks, scaredgrl's GYN says 1 year (c_nt), CDC says 6 months.
It's a no win situation. I thought I was relatively responsible, guess not...
You're cool, just get tested...you're past this fabled window period anyways.
